PEKIN — A Washington man will serve a 10-year prison term for providing the heroin that killed his customer as the victim’s teen son watched.

Anthony Montgomery, 25, became the third Tazewell County resident to be prosecuted in the past two years on charges of supplying drugs that produced fatal overdoses.

The state’s truth-in-sentencing law will require him to serve at least 75 percent of the sentence imposed two weeks ago when Montgomery entered an unscheduled guilty plea to drug-induced homicide. His next court appearance had been set for Monday.

Montgomery faced up to 30 years in prison on the Class X felony for the death last Dec. 22 of Anthony Lutes, 39, of Metamora.

The last words Lutes spoke were to his son. “I’m lit,” he said.

Lutes took his son with him to Montgomery’s home at 1308 W. Jefferson St. to ingest what became a fatal dose of heroin, according to a prosecutor’s court affidavit.

The son told police he expected to buy marijuana in the visit. When he asked Montgomery by text message earlier in the day if that drug was available, Montgomery’s reply mentioned “hero,” a term for heroin, and “flame,” and told the youth to ask his father if he wanted “flame,” the affidavit stated.

When the two arrived, Montgomery, carrying a small container, and Lutes walked into a bedroom, the youth said. Lutes clearly was intoxicated in a way his son had never seen before when he emerged five minutes later, the affidavit stated.

He told his son, “I’m lit,” then sat down and passed out. The youth and Montgomery threw water on him, but Lutes never awoke.

The youth carried his father to their car and drove to his uncle’s residence. Police were summoned and found Lutes unresponsive in the car. He was pronounced dead a short time later, the affidavit stated.

Montgomery told police he had provided heroin to Lutes in the past, but not on that day when the father and son had come to buy marijuana.

According to the charge, another man besides Montgomery injected the heroin into Lutes in the bedroom. That man has not been charged in the case.

In June 2013, Daughlton Calvin, 20, of Morton was sentenced to 27 years in state prison for the drug-induced homicides of two acquaintances who drank fatal doses of methadone, a prescription drug, that he provided.

Anthony Mansini, 23, of Pekin, awaits prosecution in federal court on a charge of conspiring to sell heroin. He allegedly sold doses of the drug that killed three people in 2012.
